Surecom SW-28HF SWR Meter 1.5-60MHz 120W for HF Ham and CB Radio Reads Forward Power, Reflected Power and VSWR, Buzzer Above 2.0, Peak or Average Hold, Switchable Layouts, USB-C Charging

FORWARD POWER, REFLECTED POWER AND VSWR - Covers 1.5 to 60MHz, which takes in the 40m, 20m and 10m amateur bands and the CB channels, with a rated maximum of 120W. A 100W transceiver sits inside that figure. Check your radio's output before connecting it. HF RANGE ONLY - NOT VHF OR UHF - The 1.5 to 60MHz window is the whole story: 2m, 70cm and anything else above 60MHz are outside it and need a meter built for that range. Buying this for a VHF or UHF rig will not work, so confirm the band you operate first. OLED READOUT, SWITCHABLE LAYOUTS - Cycle through the display arrangements with one button and settle on the one you read fastest. Normal and peak-hold modes swap over the same way. A buzzer sounds once standing wave passes 2.0, so a bad match announces itself while you are still at the key. RUNS OFF ITS OWN BATTERY - The internal lithium cell gives more than 50 hours per charge, so the meter works out in the field with nothing but a coax run either side. It tops up over the USB-C port, and accuracy is stated as better than 5%. WIRES IN LINE, 8.8 X 6.3 X 3.8CM - The meter sits between the radio and the antenna: transceiver into TX, feedline into ANT. In the box are the meter, a USB lead and the manual. Connect it while you are taking readings and unhook it afterwards rather than leaving it permanently in the run
